PHILADELPHIA (CBS) – The data from the CDC is disturbing when it comes to obesity. The obesity rate has increased from 19.4% in 2004 to 29.0% in 2012. During the same period, the prevalence of diabetes has nearly doubled from 5.1% to 9.2%.

There is good news. Americans are more active and smoke less than they did 15 years ago. Active leisure-time activities have increased from 40.3% in 1997 to 48.4% last year while smoking has dropped from 24.7% of Americans to 18 %.

It raises the question, what are we doing when it comes to our diets?

America needs to take a careful look at the food it consumes.
